help with java code please! * File: Donor.java * * Description: This class represents a donor to an * organization. It stores the donor's name and rating. * The main() method tests the class's methods. * * Assignment: * 1) Add a new level "low" to this class (in addition to * "high", "medium", "none") * 2) Add a new method: * public void updateRating(double amt){ } which recalculates * a donor's rating according to the following schedule: * a) amt = 0 - none * b) amt < $100 - low level * c) amt >= $100 and amt < $1000 - medium level * d) amt >= $1000 - high level * updateRating() should change the instance variable: * rating to the new value * 3) Modify this template to include an address variable and * change the constructor to accept this new variable * (along with the parameters). Basically, the object * stores the donor's name, address and rating * 4) Modify main() to print out donor address also * 5) Create a new donor (donor4) with an initial "low" rating, * a) then let donor4 contribute $150, * b) print this donor's new rating to the console * 6 Modify the rest of the program (as needed) so that it * compiles and runs correctly * */ /** * * @author put-your-name-here * */ public class Donor { private String name = "no name"; private String rating = "none"; /** * Donor() constructor sets the object's name and rating * @param str -- a String giving the donor's name * @param str2 -- a String giving the donor's rating */ public Donor(String str, String str2) { name = str; rating = str2; // Hint: add address string here } /** * getName() returns the donor's name * @return a String giving the person's name */ public String getName() { return name; } // Hint: add accessor method to get the address /** * getRating() returns the donor's rating * @return a String giving the person's rating */ public String getRating() { // This if could be a switch/case conditional // add check for low level if (rating.equals("high")) { return "high"; } else if (rating.equals("medium")) { return "medium"; } else { return "none"; } } /** * main() creates three Donor instances and tests this classes methods. */ public static void main (String argv[]) { // Hint: add address string to the three (3) constructors Donor donor1 = new Donor("put-donor1-name-here", "high"); // Hint: add address string to the output System.out.println("Donor's name is " + donor1.getName()); System.out.println(donor1.getName() + "'s rating is " + donor1.getRating()); Donor donor2 = new Donor("put-donor2-name-here", "medium"); System.out.println("Donor's name is " + donor2.getName()); System.out.println(donor2.getName() + "'s rating is " + donor2.getRating()); Donor donor3 = new Donor("put-donor3-name-here", "none"); System.out.println("Donor's name is " + donor3.getName()); System.out.println(donor3.getName() + "'s rating is " + donor3.getRating()); // add code to construct donor4 and print donor4 info // add code to increase donor4's amount (updateRating()) // and print out new donor4 rating } // end main() } // end Donor class
